A system (ESCGV) for increasing the clarity of the field of view for gastrointestinal endoscopy includes a cleaning bottle (1) and a liquid transport tube (2) extending from the cleaning bottle (1), the liquid transport tube (2) comprising: The cleaning liquid is pumped to the water supply system of the gastrointestinal endoscope or the observation window of the gastrointestinal endoscope through the first peristaltic pump (3), and the cleaning bottle (1) is capable of stirring and heating the cleaning liquid. A system is further provided. In addition, the method of increasing the clarity of the field of view for gastrointestinal endoscopy includes 1) a step of putting a cleaning liquid into the cleaning bottle (1), and 2) cleaning while magnetically stirring the cleaning liquid in the cleaning bottle (1). Heating the cleaning liquid in the bottle (1), 3) setting the temperature of the cleaning liquid to 25 to 38 ° C., and 4) pumping the cleaning liquid to the observation window of the gastrointestinal endoscope. The above-mentioned system for increasing the visibility of the gastrointestinal endoscope medical field can improve the clarity of the field of view of the gastrointestinal endoscope, is easy and convenient to operate, and reduces the occurrence of omissions and misdiagnosis. Can improve the quality of medical treatment by gastrointestinal endoscope. [Selection] Figure 1胃腸内視鏡診療用視野の鮮明度を高めるシステム（ＥＳＣＧＶ）は、洗浄ボトル（１）及び洗浄ボトル（１）から伸びた液体輸送チューブ（２）を含み、前記液体輸送チューブ（２）が、第１蠕動ポンプ（３）を介して洗浄液を胃腸内視鏡の給水システム又は胃腸内視鏡の観察窓へポンピングし、洗浄ボトル（１）が、洗浄液に対して攪拌及び加熱可能な攪拌加熱サブシステムを更に備える。また、胃腸内視鏡診療用視野の鮮明度を高める方法は、１）洗浄ボトル（１）内に洗浄液を入れるステップ、２）洗浄ボトル（１）内の洗浄液に対して磁気攪拌しながら、洗浄ボトル（１）内の洗浄液を加熱するステップ、３）洗浄液の温度を２５～３８℃とするステップ、４）洗浄液を胃腸内視鏡の観察窓へポンピングするステップ、を含む。上記の胃腸内視鏡診療用視野の鮮明度を高めるシステムでは、胃腸内視鏡の視野の鮮明度を向上させることができ、操作が簡単で便利であり、診断漏れと誤診の発生を低減させ、胃腸内視鏡による診療の品質を向上させることができる。【選択図】図１
